J Pediatr Surg. 2003;38(5):788-792. Observational-Tx 98 CVCs, 52 external tunneled catheters, 46 subcutaneous ports, in 67 patients To compare the frequency of delayed complications in CVCs placed surgically or radiologically in a pediatric oncology population. Median patient age was 6.1 years for children with external catheters and 7.8 years for those with ports. Both infectious and mechanical complications were significantly more common among surgically placed ETCs than those placed radiologically (P <.05). Complications per 1,000 catheter days and premature removal showed a trend toward greater frequency among surgical ETCs, although this did not reach statistical significance. No consistent trends were seen in complications among ports. 2

AJR Am J Roentgenol. 2012;199(2):447-452. Review/Other-Tx 512 complete datasets of procedures To retrospectively evaluate radiologically totally implanted central venous access ports (VAPs) of the upper arm in terms of safety, technical feasibility, and device-related complications. In 507 patients, a total of 523 devices were implanted. Of these 523 procedures, 512 complete datasets were available during follow-up. The primary technical success rate was 99.04%. All procedures were completed without major complications. During follow-up and with a total number of 127,750 days of totally implanted central VAP implantation (248 +/- 279 days/patient; range, 1-1687 days/patient), 50 devices had to be revised because of complications (9.8%). Complications occurred at a mean of 114 +/- 183 days (range, 1-1113 days) after placement. Early complications were noted in 21 of 512 cases (4.1%), and late complications were noted in 29 of 512 cases (5.7%). Complications were as follows: local infections, 4.9% (25/512); systemic infections, 0.4% (2/512); venous thrombosis, 1.6% (8/512); paralysis of the median nerve, 0.6% (3/512); skin dehiscence at the port site, 0.2% (1/512); and mechanical problems including catheter line displacement, port hub rotation, and catheter fracture, 2.1% (11/512). 4

Percutaneous placement of central venous catheters: comparing the anatomical landmark method with the radiologically guided technique for central venous catheterization through the internal jugular vein in emergent hemodialysis patients. Acta Radiol. 2006;47(1):43-47. Experimental-Tx 40 anatomical landmark method; 40 radiologically guided technique To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients. The groups were comparable in age and sex. The indication for catheter placement was hemodialysis access in all patients. Catheter placement was successful in all patients in group 2 and unsuccessful in 1 (2.5%) patient in group 1. All catheters functioned adequately and immediately after the placement (0% initial failure rate) in group 2, but 3 catheters (7.5% initial failure rate) were non-functional just after placement in group 1. The total number of needle passes, double venous wall puncture, and complication rate were significantly lower in group 2. 1

J Vasc Interv Radiol. 2001;12(10):1211-1214. Review/Other-Tx N/A To determine the percentage of venous access procedures performed by each specialty in the last 5 years and to evaluate trends in venous access. A secondary goal was to track overall growth of venous access procedures in IR. The authors determined changing trends and growth in tunneled and nontunneled central venous catheter placement procedures. With use of Medicare billing data for tunneled and nontunneled catheter placement, a comparison was made among interventional radiology (IR), surgery, anesthesia, and internal medicine. There has been substantial growth in the placement of central venous catheters. Currently, a minority of these procedures are performed in IR departments. However, there has been significant growth in the radiologic placement of both types of catheters. 4

Eur Radiol. 2011;21(6):1224-1232. Review/Other-Tx 3,160 port catheter systems To evaluate the success and complication rates after radiologically guided port catheter implantation. 922,599 catheter days (mean, 292 days; range, 0-2,704 days) were documented. The implantation was successful in 3,153 (99.8%) cases. A total of 374 (11.8%; 0.41/1,000 catheter days) adverse events were recorded. Of these, 42 (1.33%) were periprocedural complications. 86 (3.3%; 0.09/1,000 catheter days) early and 246 (9.4%; 0.27/1,000 catheter days) late onset complications occurred after port implantation. The most common complications were blood stream infection (n = 134; 5.1%; 0.15/1,000 catheter days), catheter-induced venous thrombosis (n = 97; 3.7%; 0.11/1,000 catheter days) and catheter migration (n = 34; 1.3%; 0.04/1,000 catheter days). A total of 193 (6.1%) port explantations were required. 4

Meta-analysis 15 studies; 6,199 catheters To determine the risk of catheter-related bloodstream infection (CRBSI) and catheter colonization in multilumen catheters compared with single-lumen catheters. A total of 15 studies met inclusion criteria. Summary odds ratios were calculated using a random-effects model. Although CRBSI was more common in multilumen catheters (summary odds ratios, 2.15; 95% confidence interval, 1.00-4.66), catheter colonization was not (summary odds ratios, 1.78; 95% confidence interval, 0.92-3.47). Tests for heterogeneity, however, suggested substantial variation by study. When only studies of higher quality were included, multilumen catheters were found not to be associated with a significant increase in CRBSI prevalence (summary odds ratios, 1.30; 95% confidence interval, 0.50-3.41).

9. Knutstad K, Hager B, Hauser M. Radiologic diagnosis and management of complications related to central venous access. Acta Radiol. 2003;44(5):508-516. Review/Other-Tx N/A To provide an overview of different types of delayed CVC complications and discuss therapeutic options based on interventional radiology techniques. Radiology plays a central role in the management of patients with CVCs. In most cases radiologic modalities will provide the cause of catheter dysfunction or catheter-related venous thrombosis, as well as the location of intravascular foreign bodies. For all these conditions, various interventional radiologic techniques with a low complication risk can be offered. These techniques will eventually lead to extended catheter survival. With respect to more advanced CVC systems such as tunneled catheters or VAPs, device removal and reinsertion can often be obviated. In patients with technically challenging venous anatomy or increased risk for complications, image-guided insertion should be the method of choice. 4

Clin Nutr. 2009;28(4):365-377. Review/Other-Tx N/A To provide general recommendations about the indications for and the use of the different types of venous access devices available for parenteral nutrition. The most appropriate site for central venous access will take into account many factors, including the patient's conditions and the relative risk of infective and non-infective complications associated with each site. Ultrasound-guided venepuncture is strongly recommended for access to all central veins. For parenteral nutrition, the ideal position of the catheter tip is between the lower third of the superior cava vein and the upper third of the right atrium; this should preferably be checked during the procedure. Catheter-related bloodstream infection is an important and still too common complication of parenteral nutrition. The risk of infection can be reduced by adopting cost-effective, evidence-based interventions such as proper education and specific training of the staff, an adequate hand washing policy, proper choices of the type of device and the site of insertion, use of maximal barrier protection during insertion, use of chlorhexidine as antiseptic prior to insertion and for disinfecting the exit site thereafter, appropriate policies for the dressing of the exit site, routine changes of administration sets, and removal of central lines as soon as they are no longer necessary. Most non-infective complications of central venous access devices can also be prevented by appropriate, standardized protocols for line insertion and maintenance. These too depend on appropriate choice of device, skilled implantation and correct positioning of the catheter, adequate stabilization of the device (preferably avoiding stitches), and the use of infusion pumps, as well as adequate policies for flushing and locking lines which are not in use. 4

Gauze, a transparent polyurethane dressing, and an iodophor-transparent dressing. JAMA. 1987;258(17):2396-2403. Experimental-Tx 2,088 catheters from 1,259 patients To study in a prospective randomized clinical trial four dressing regimens for peripheral venous catheters with 2088 Teflon catheters. The four dressings provided comparable coverage, except moisture accumulated more frequently under the transparent dressings (26% to 28% vs 20% to 21%). Cutaneous colonization under the dressing was low level and comparable with all four dressings (range, 10(0.58) to 10(0.70) colony-forming units). The rate of local catheter-related infection (greater than or equal to 15 colony-forming units) was also low and did not differ significantly (range, 4.6% to 5.9%); no catheter caused bacteremia. Stepwise logistic multivariate analysis showed cutaneous colonization of the insertion site (relative risk [RR] of infection, 3.86), contamination of the catheter hub (RR, 3.78), moisture under the dressing (RR, 2.48), and prolonged catheterization (RR, 1.75) to be significant risk factors for catheter-related infection. 1

J Clin Microbiol. 1983;18(5):1061-1063. Observational-Tx 687 Teflon and 77 polyvinyl chloride catheters To analyze differences in rates of bacterial colonization of PVC and TEF catheters during clinical use and to compare the bacterial species involved. Of the 687 Teflon catheters cultured, 6.9% were positive by culture, compared with 24.6% of 77 polyvinyl chloride catheters (P less than 0.001). Also, colonization of coagulase-negative staphylococci on polyvinyl chloride was more than on Teflon. These data suggest that polyvinyl chloride catheters are colonized more frequently with organisms than are Teflon catheters; additionally, there is an increased affinity of coagulase-negative staphylococci for polyvinyl chloride as compared with Teflon, substantiating our previous observations with an in vitro system. 2

Review/Other-Tx N/A To review the literature on prevention of intravascular catheter-related infections. The recommended preventive strategies with the strongest supportive evidence are full barrier precautions during central venous catheter insertion; subcutaneous tunneling short-term catheters inserted in the internal jugular or femoral veins when catheters are not used for drawing blood; contamination shields for pulmonary artery catheters; povidone-iodine ointment applied to insertion sites of hemodialysis catheters; specialized nursing teams caring for patients with short-term peripheral venous catheters, especially at institutions with a high incidence of catheter-related infection; no routine replacement of central venous catheters; antiseptic chamberfilled hub or hub-protective antiseptic sponge for central venous catheters; and use of chlorhexidine-silver sulfadiazine-impregnated or minocycline-rifampin-impregnated short-term central venous catheters if the rate of infection is high despite adherence to other strategies that do not incorporate antimicrobial agents (for example, maximal barrier precautions). 4

JAMA. 1999;281(3):261-267. Meta-analysis 12 studies; 2,611 catheters - catheter colonization 11 studies; 2,603 catheters - catheter-related bloodstream infection To evaluate the efficacy of chlorhexidine-silver sulfadiazine-impregnated central venous catheters in the prevention of catheter-related bloodstream infection. The summary odds ratio for catheter colonization was 0.44 (95% confidence interval [CI], 0.36-0.54; P<.001), indicating a significant decrease in catheter colonization associated with impregnated catheters. The studies examining the outcome of primary interest, catheter-related bloodstream infection, had a summary odds ratio of 0.56 (95% CI, 0.37-0.84; P = .005). M

Prevention of intravascular catheter-related infection with newer chlorhexidine-silver sulfadiazine-coated catheters: a randomized controlled trial. Intensive Care Med. 2004;30(5):837-843. Experimental-Tx 363 patients with catheter insertion To test the ability of the new generation of chlorhexidine-silver and sulfadiazine-coated catheters, with enhanced antiseptic coating, to reduce the risk of central venous catheter (CVC)-related infection in ICU patients. Of 367 patients having a successful catheter insertion, 363 were analysed (175 NCC and 188 ACC). Patients had one (NCC=162, ACC=180) or more (NCC=13, ACC=11) CVC inserted. The two groups were similar for insertion site [subclavian (64 vs 69)] or jugular (36 vs 31%)], and type of catheters (single-lumen 18 vs 18%; double-lumen 82 vs 82%), and mean (median) duration of catheterisation [12.0+/-11.7 (9) vs 10.5+/-8.8 (8) days in the NCC and ACC groups, respectively]. Significant colonisation of the catheter occurred in 23 (13.1%) and 7 (3.7%) patients, respectively, in the NCC and ACC groups (11 vs 3.6 per 1000 catheter-days; p=0.01); CVC-related infection (bloodstream infection) occurred in 10 (5) and 4 (3) patients in the NCC and CC groups, respectively (5.2 vs 2 per 1000 catheter days; p=0.10). 1

Chlorhexidine and silver-sulfadiazine coated central venous catheters in haematological patients--a double-blind, randomised, prospective, controlled trial. Support Care Cancer. 2005;13(12):993-1000. Experimental-Tx 184 catheters, of which 90 were antiseptically coated To investigate a novel version of chlorhexidine and silver sulfadiazine coated catheters in a prospective, double-blind trial to determine the efficacy of antiseptic coating in preventing catheter-related infections amongst haematological patients undergoing chemotherapy. Catheters coated with CHSS were effective in reducing the rate of significant bacterial growth on either the tip or subcutaneous segment (26%) compared to control catheters (49%). The incidence of catheter colonisation was also significantly reduced (12% coated vs 33% uncoated). Data obtained show a significant reduction of catheter colonisation in CHSS catheters. There was no significant difference in the incidence of catheter-related bacteraemia (3% coated vs 7% uncoated). However, due to the overall low rate of CRI, we could not observe a significant reduction in the incidence of catheter-related bacteraemia. 1

Effect of a second-generation venous catheter impregnated with chlorhexidine and silver sulfadiazine on central catheter-related infections: a randomized, controlled trial. Ann Intern Med. 2005;143(8):570-580. Experimental-Tx 780 patients To ascertain 1) effectiveness of a second-generation antiseptic-coated catheter in the prevention of microbial colonization and infection; 2) safety and tolerability of this device; 3) microbiology of infected catheters; and 4) propensity for the development of antiseptic resistance. Patients with the 2 types of catheters had similar demographic features, clinical interventions, laboratory values, and risk factors for infection. Antiseptic catheters were less likely to be colonized at the time of removal compared with control catheters (13.3 vs. 24.1 colonized catheters per 1000 catheter-days; P < 0.01). The center-stratified Cox regression hazard ratio for colonization controlling for sampling design and potentially confounding variables was 0.45 (95% CI, 0.25 to 0.78). The rate of definitive catheter-related bloodstream infection was 1.24 per 1000 catheter-days (CI, 0.26 to 3.62 per 1000 catheter-days) for the control group versus 0.42 per 1000 catheter-days (CI, 0.01 to 2.34 per 1000 catheter-days) for the antiseptic catheter group (P = 0.6). Coagulase-negative staphylococci and other gram-positive organisms were the most frequent microbes to colonize catheters. Noninfectious adverse events were similar in both groups. Antiseptic susceptibility was similar for microbes recovered from either group. 1
19. Darouiche RO, Raad, II, Heard SO, et al. A comparison of two antimicrobial-impregnated central venous catheters. Catheter Study Group. N Engl J Med. 1999;340(1):1-8. Experimental-Tx 738 catheters To compare catheters impregnated with minocycline and rifampin with those impregnated with chlorhexidine and silver sulfadiazine in terms of the rates of colonization of catheters and bloodstream infection. Of 865 catheters inserted, 738 (85 percent) produced culture results that could be evaluated. The clinical characteristics of the patients and the risk factors for infection were similar in the two groups. Catheters impregnated with minocycline and rifampin were 1/3 as likely to be colonized as catheters impregnated with chlorhexidine and silver sulfadiazine (28 of 356 catheters [7.9 percent] vs. 87 of 382 [22.8 percent], P<0.001), and catheter-related bloodstream infection was 1/12 as likely in catheters impregnated with minocycline and rifampin (1 of 356 [0.3 percent], vs. 13 of 382 [3.4 percent] for those impregnated with chlorhexidine and silver sulfadiazine; P<0.002). 1

Long-term silicone central venous catheters impregnated with minocycline and rifampin decrease rates of catheter-related bloodstream infection in cancer patients: a prospective randomized clinical trial. J Clin Oncol. 2004;22(15):3163-3171. Experimental-Tx 356 assessable catheters: 182 M-R and 174 nonimpregnated To evaluate the efficacy of long-term nontunneled silicone catheters impregnated with minocycline and rifampin (M-R) in reducing catheter-related bloodstream infections. Between September 1999 and May 2002, 356 assessable catheters were used: 182 M-R and 174 nonimpregnated. The patients' characteristics were comparable between the two study groups. The mean (+/- standard deviation) duration of catheterization with M-R catheters was comparable to that of nonimpregnated catheters (66.21 +/- 30.88 v 63.01 +/- 30.80 days). A total of 17 catheter-related bloodstream infections occurred during the course of the study. Three were associated with the use of M-R catheters and 14 were associated with the nonimpregnated catheters, with a rate of catheter-related bloodstream infection of 0.25 and 1.28/1,000 catheter-days, respectively (P = .003). Gram-positive cocci accounted for the majority of the organisms causing the infections. There were no allergic reactions associated with M-R catheters. 1

J Clin Pathol. 2003;56(10):731-735. Experimental-Tx 304 single lumen study catheters in 268 patients To evaluate the efficacy of silver iontophoretic central venous catheters in preventing catheter related colonisation and bloodstream infection among high risk patients in a tertiary hospital. Three hundred and four single lumen study catheters were inserted into 268 patients. Total duration of catheterisation was 5449 days (median, 12 days/catheter). Complete data could be evaluated in 270 catheters: 128 silver iontophoretic catheters and 140 untreated catheters. Forty seven silver iontophoretic catheters (36.7%) were colonised compared with 48 control catheters (33.8%). Seven cases (5.5%) of CRBSI occurred in patients who received silver iontophoretic catheters, compared with 11 cases (7.7%) in patients receiving control catheters. There was no significant difference in the incidence of catheter colonisation or CRBSI between silver iontophoretic and control catheters. When the duration of catheter placement was taken into consideration, Kaplan-Meier analysis showed no significant difference in the risk of CRBSI between the silver iontophoretic catheters and the untreated catheters (p = 0.77). 1

Experimental-Tx 206 catheters, 103 each of standard polyurethane CVC or Oligon Vantex silver CVC To determine whether bacterial colonization and CR-BSI were associated with the use of the OVSC in critically ill patients. In the control group (CG) 45/103 (44%) and in the silver group (SG) 30/103 (29%) were colonized or had a CR-BSI (P=0.04). The SG was less likely to be colonized than the CG when the catheter remained in situ for eight days or less (P=0.03) or over 15 days (P=0.01); a second or subsequent catheter was present in the same patient (P=0.002), or if the CVC was placed in the internal jugular vein (P=0.05). Multivariate logistic-regression showed predisposing factors for catheter colonization were jugular and femoral sites, second or subsequent catheter, and being a member of the CG. CR-BSI occurred in five cases (four in CG). Rates of CR-BSI per 1000 catheter-days in the CG were 2.8 and in the SG, 0.8 (P<0.001). 1

Central venous catheter colonization and catheter-related bloodstream infections in critically ill patients: a comparison between standard and silver-integrated catheters. Eur J Anaesthesiol. 2009;26(9):752-758. Experimental-Tx 272 catheters inserted into 230 patients (141 standard and 131 silver-integrated central venous catheters) To investigate colonization and infection rates of standard central venous catheters in comparison with the rates for silver-integrated catheters in the intensive care unit. There was no significant difference in the colonization rates and the colonization per 1000 catheter days between the standard and silver-integrated catheters. Using the Kaplan-Meier curves (long-rank test), there was a significant difference in the incidence of colonization and infections over time between standard and silver-integrated catheters (P<0.01 and P<0.05, respectively). Whereas standard catheters were first colonized 3 days after the insertion, silver-integrated catheters were first colonized 5 days after insertion. 1

Observational-Tx 175 tunneled dialysis catheters placed in the internal jugular vein, including 89 heparin-coated catheters and 86 noncoated catheters To evaluate whether heparin-coated hemodialysis catheters have fewer infections or greater cumulative survival than noncoated catheters. The two patient groups were similar in demographics and clinical and catheter features. Catheter-related bacteremia occurred less frequently with heparin-coated catheters than with noncoated catheters (34 versus 60%, P < 0.001). Cumulative catheter survival was similar in heparin-coated and noncoated catheters (hazard ratio, 0.87; 95% confidence interval, 0.55 to 1.36; P = 0.53). On multiple variable survival analysis including catheter type, age, sex, diabetes, coronary artery disease, peripheral vascular disease, cerebrovascular disease, catheter location, and previous catheter, only catheter location predicted cumulative catheter survival (hazard ratio, 2.03; 95% CI, 1.27 to 3.25, with the right internal jugular location being the reference group, P = 0.003). The frequency of thrombolytic instillation was 1.8 per 1000 catheter-days in both groups. 2

Experimental-Tx 200 patients - 97 with heparin-bonded, 103 standard To determine whether heparin bonding reduces the incidence of catheter-related thrombosis and infection in critically ill children. The two groups were comparable for age, sex, severity of illness and length of time that the catheter was in situ. Proportional hazards modelling showed that heparin bonding was associated with a significant reduction in infections (hazard ratio 0.11, P < 0.00005). The incidence of infection was 4% and 33% in HB and NHB CVLs, respectively (4/97 vs. 34/103, P < 0.0005). The incidence of thrombosis was 0% and 8% in HB and NHB CVLs, respectively (0/97 vs. 8/103, P = 0.006). The number of HB CVLs which would need to be used to avoid one episode of infection or thrombosis was 3 and 13, respectively. 1

Cancer. 2001;92(5):1204-1212. Experimental-Tx 302 patients (150 control; 152 experimental) To investigate valved and open-ended catheters in a randomized trial using the same type of subcutaneous port and evaluate efficacy as well as early and late complications Three hundred two patients (99.3%) were evaluable, 150 patients in the control group and 152 in the experimental group. The median follow-up was 237 days. There was a trend toward more early complications in the experimental group (5.9%; 95% confidence interval [95% CI], 2.7-10.9%) than in the control group (2.7%; 95% CI, 0.7-6.7%), although the difference was not statistically significant (P = 0.26). There was also a trend toward more late complications in the experimental group (17.1%; 95% CI, 11.5-24.1%) compared with the control group (10.7%; 95% CI, 6.2-16.7%; P = 0.13), although the difference, again, was not statistically significant. The most frequent late complication was the inability to draw blood samples (12.5% in the experimental group and 2% in the control group; P < 0.001). Sepsis was observed in 1 patient and in 3 patients and venous thrombosis was observed in 6 patients and in 11 patients in the experimental and control treatment groups, respectively (P value not significant). 1

Experimental-Tx 69 catheters and 69 patients To prospectively compare two types of hemodialysis catheter currently available: the PermCath catheter with a staggered tip design and the newer split-tip lumen style Ash Split catheter. A total of 69 hemodialysis catheters, 33 AS and 36 PC, were successfully inserted in the internal jugular vein (right 60, left 9) of 69 patients. Mean blood flow during dialysis (Qb) was 270.75 ml/min and 261.86 ml/hr for the AS and PC groups respectively (p = 0.27). Mean duration of catheter use was 111.7 days (range 5.4-548.9 days) and 141.2 days (range 7.0-560.9 days) in the AS and PC groups respectively (p = 0.307). Catheter failures leading to removal or exchange occurred in 20 patients: 14 in the AS group and six in the PC group. Survival curves with censored endpoints (i.e., recovery, arteriovenous fistula formation, peritoneal dialysis and transplantation) showed significantly better outcome with PermCath catheters (p = 0.024). There was no significant difference in ease of insertion or early complication rates. 1

Observational-Tx 54 patients To compare flow rates, infection rate, and survival of side hole vs. non side hole hemodialysis catheters. Catheter infection necessitating removal of the catheter occurred in 10/37 catheters with side holes and 1/17 without side holes. Infection rates per 1,000 catheter days were 2.545 with side holes and 0.254 without side holes (p<0.001). Slightly improved catheter survival (p<0.05) was recorded with the non side hole catheters. No insertion complication (e.g., air embolization, bleeding, or kinking) occurred with either catheter. One catheter without side holes had to be repositioned 5 days after insertion because of poor flows. No significant difference was recorded in mean blood flow rates between the catheters. 2

Experimental-Tx 80 patients To study the immediate and long-term performance and complications of two twin-catheter systems, the Tesio catheter (TC) and the LifeCath Twin (LC), to inform clinical practice. More LCs reached the primary endpoint (44% vs. 10%, p=0.001) delivering a higher BFR (mean 383+/-82 vs. 277+/-79 mL/min, p<0.001). Significant differences in BFR persisted until the fourth dialysis session. Rates of catheter-related bacteremia (0.40 vs. 0.51/1,000 catheter days, p=0.7) and exit site infection were similar between groups (0.24 vs. 0.09/1,000 catheter days, p=0.4). Overall rates of catheter dysfunction were 2.8/1,000 catheter days (95% CI 2.1-3.5), with no differences in thrombolytic lock use although the LC group required more thrombolytic infusions (6 vs. 0, p=0.01). 1

Experimental-Tx Phase A: 15 patients; Phase B: 11 patients To compare the nutritional value of three parenteral fluids: a conventional solution (400 milliosmoles/liter, containing Na, K, and Cl in 5% glucose); the concentrated hyperalimentation solution of Dudrick (1,800 milliosmoles/liter, containing Na, K, Cl, Mg, Ca, P, and amino acids in 20% glucose); and an experimental solution (900 millisomoles/liter, containing Na, K, Cl, Mg, Ca, P, and amino acids in 6.5% glucose). Preliminary studies showed that when 5 mg of cortisol/liter were added to P900, this fluid could be infused through peripheral veins for as long a time (average 114 hr) as P400 before local reaction necessitated changing the site. When P400 was infused in undernourished subjects without oral intake, balances of N, P, Mg, and Ca/70 kg of body weight per day were strongly negative (-4 g, -0.4 g, -6 mEq, and -0.2 g, respectively), whereas balances of K were about zero and those of Na and Cl were positive. Weight loss occurred. In the same patients, P900 containing 5 mg of cortisol/liter converted balances of N, P, Mg, and K to positive, and stimulated weight gain. Comparison of P900 (containing cortisol) and C1,800 in three emaciated subjects showed that the latter fluid caused a 2 to 4 times greater degree of positive balance in N, P, K, and Mg than the former. Comparison of P900 (containing cortisol) + 670-1700 cal by mouth with C1,800 in four undernourished subjects showed no statistically significant difference between these two programs. 1

Arch Intern Med. 1993;153(15):1791-1796. Observational-Tx 340 consecutive cancer patients with 359 nontunneled Silastic CVCs To assess the durability, cost, and infection rate of nontunneled, noncuffed Silastic CVCs. The mean in-place duration of the catheter for the 359 nontunneled CVCs studied was 109 days (total, 39,147 days of catheter use), and the infection rate was 0.13 per 100 catheter days. When compared with the tunneled Hickman catheter, the insertion cost saving was at least $2322 per CVC. At our institution, the use of nontunneled Silastic catheters with the support of an expert infusion team has resulted in an annual cost saving of at least $7,692,000. Long peripheral CVCs (in the basilic/cephalic vein) had a 26% rate of inflammation at the insertion site compared with only 2.6% for the short subclavian CVCs (P < .01). Most of the exit-site inflammations were sterile, with negative skin and catheter cultures. Neutropenia, bone marrow transplantation, high-dose steroids, and use of vesicant chemotherapeutic agents through the CVC did not predispose the patients to catheter infection. By univariate analysis, acute leukemia was the only risk factor for catheter infection. 2

Mayo Clin Proc. 2006;81(9):1159-1171. Meta-analysis 200 studies To better understand the absolute and relative risks of bloodstream Infection (BSI) associated with the various types of intravascular devices (IVDs) by analyzing 200 published studies of adults in which every device in the study population was prospectively evaluated for evidence of associated infection and microbiologically based criteria were used to define IVD-related BSI. Point incidence rates of IVD-related BSI were lowest with peripheral Intravenous catheters (0.1%, 0.5 per 1000 IVD-days) and midline catheters (0.4%, 0.2 per 1000 catheter-days). Far higher rates were seen with short-term noncuffed and nonmedicated central venous catheters (CVCs) (4.4%, 2.7 per 1000 catheter-days). Arterial catheters used for hemodynamic monitoring (0.8%, 1.7 per 1000 catheter-days) and peripherally inserted central catheters used in hospitalized patients (2.4%, 2.1 per 1000 catheter-days) posed risks approaching those seen with short-term conventional CVCs used in the Intensive care unit. Surgically implanted long-term central venous devices--cuffed and tunneled catheters (22.5%, 1.6 per 1000 IVD-days) and central venous ports (3.6%, 0.1 per 1000 IVD-days)--appear to have high rates of Infection when risk Is expressed as BSIs per 100 IVDs but actually pose much lower risk when rates are expressed per 1000 IVD-days. The use of cuffed and tunneled dual lumen CVCs rather than noncuffed, nontunneled catheters for temporary hemodlalysis and novel preventive technologies, such as CVCs with anti-infective surfaces, was associated with considerably lower rates of catheter-related BSI.

J Clin Oncol. 1999;17(4):1267. Experimental-Tx 199 assessable patients To examine the safety, efficacy, costs, and impact on quality of life of venous access ports implanted at the outset of a course of intravenous cancer chemotherapy. Port complication rates were low (0.23/1,000 days). Failure occurred in two (3.4%) of 59 port subjects and 16 (26.7%) of 60 controls (P =. 0004) at a median period of 26 days after randomization (95% confidence interval, 8 to 92). Peripheral accesses in port subjects took less time, had less access-related anxiety and pain, and were less costly to perform than in controls. Allocation had no effect on FLI-C scores. Peripheral access failure correlated with allocation to the control group (P =.007), higher pain scores with intravenous (IV) starts (P =.003), and anxiety with IV starts (P =.01). Venous accessing overall in port patients was four times more costly than that in controls ($2,178/patient v $530/patient, respectively). 1

Observational-Tx 440 implantable chest or arm ports in 422 patients To determine the risk of deep venous thrombosis (DVT) in patients undergoing placement of central (chest) versus peripheral (arm) ports. In 273 chest ports placed, there were 13 (4.8%) instances of DVT; in 149 peripheral ports, there were 17 (11.4%). Censoring data on patients receiving some form of anticoagulation, the respective incidences were eight of 245 (3.3%) and 14 of 129 (10.9%). With use of Kaplan-Meier analysis and log-rank tests to examine comparisons of interest, the probability of thrombosis occurring over a period of 180 days was higher with peripheral ports irrespective of Coumadin use (P =.007 for all patients considered, P =.002 when analyzed only for those not receiving Coumadin). The difference in incidence of thrombosis for all ports between patients receiving Coumadin versus those not receiving Coumadin was not significant. 2

Experimental-Tx 70 patients To compare the safety and cost of two commonly used CVCs, peripherally inserted central venous catheter (PICCs) and ports, in the delivery of chemotherapy in patients with non-haematological malignancies. Port devices were associated with fewer complications compared with PICC lines (hazard ratio of 0.25, CI, 0.09-0.86, P = 0.038). Major complication rate was lower in the port arm compared to the PICC arm (0.047 versus 0.193 major complications/100 catheter days, P = 0.034) with 6 versus 20 % of patients experiencing major complications, respectively. Thrombosis, the most common complication, was significantly higher in the PICC arm compared to the port arm (25 versus 0 %, P = 0.013). Quality of life and cost estimates did not differ significantly between the two arms. 1

Meta-analysis 5 RCTs and 25 observational studies To evaluate the risks of complications (infectious and non-infectious) including the need for device removal associated with centrally inserted external catheters compared with totally implantable ports in patients undergoing chemotherapy. Overall, five RCTs and 25 observational studies were included in the study. The studies were heterogeneous, and included adults and children, with different types of cancer, undergoing chemotherapy. Based on the pooled estimates from included studies, external catheters were associated with approximately a three to four-fold increase in the risks of infections, non-infectious complications and device removal compared implantable ports.

Observational-Tx 1,366 patients, 2,101 catheters To assess the risk factors associated with CR-BSI development in critically ill patients with non-tunneled, non-cuffed central venous catheters (CVC) and the prognosis of the episodes of CR-BSI. Design and setting; prospective, observational, multicenter study in nine Spanish Hospitals. Overall, 1,366 patients were enrolled and 2,101 catheters were analyzed. Sixty-six episodes of CR-BSI were diagnosed. The incidence of CR-BSI was significantly higher in CVC compared with peripherically inserted central venous catheters (PICVC) without significant differences among the three locations of CVC. In the multivariate analysis, duration of catheterization and change over a guidewire were the independent variables associated with the development of CR-BSI whereas the use of a PICVC was a protective factor. Excluding PICVC, 1,598 conventional CVC were analyzed. In this subset, duration of catheterization, tracheostomy and change over a guidewire were independent risk factors for CR-BSI. A multivariate analysis of predictors for mortality among 66 patients with CRSI showed that early removal of the catheter was a protective factor and APACHE II score at the admission was a strong determinant of in-hospital mortality. 2

World J Surg. 2006;30(8):1605-1619. Review/Other-Tx 48 studies To compare the associated infectious, thrombotic, phlebitic, and other common complications, as well as PICC and CVC durability. Our results show that infectious complications do not significantly differ between PICC and CVC. Thrombotic complications appear to be more significant with PICC and to occur early after catheterization. Phlebitic complications accounted for premature catheter removal in approximately 6% of PICC. Finally, prospective data suggest that approximately 40% of PICC will have to be removed before completion of therapy, possibly more often and earlier than CVC. 4

Observational-Tx 300 catheters in 204 patients To determine the influence of catheter site and type (single- vs triple-lumen) on infection rates associated with central venous catheterization. Three hundred catheters were inserted into 204 patients. Seventy percent were inserted into upper-body sites, and 30% were inserted into the femoral vein. Forty-five percent were triple-lumen catheters. Bacteremia occurred in 2.7% of catheter insertions; insertion-site infections developed in 1.3%, and catheter colonization developed in 12%. Catheter contamination was associated with emergent insertion (odds ratio [OR], 6.2; 95% confidence interval [CI95], 1.1-36.7; P=.04) by logistic regression and with femoral location (hazard, 4.2; CI95, 2.0-8.8; P=.0001) and history of transplantation (hazard, 2.8; CI95, 1.1-6.7; P=.024) by Cox regression. Clinical infection was not associated with any of the risk factors evaluated, although there was a trend for association with femoral location by Cox regression (hazard, 4.7; CI95, 0.82-26; P=.08). We did not identify an association between infection and use of triple-lumen catheters or parenteral nutrition. 2

Observational-Tx 2,018 patients To analyze the incidence of catheter-related local infection (CRLI) and catheter-related bloodstream infection (CRBSI) with central venous catheters (CVCs) according to different access sites. The study included 2,018 patients. The number of CVCs and days of catheterization duration were: global, 2,595 and 18,999; subclavian, 917 and 8,239; jugular, 1,390 and 8,361; femoral, 288 and 2,399. CRLI incidence density was statistically higher for femoral than for jugular (15.83 versus 7.65, p < 0.001) and subclavian (15.83 versus 1.57, p < 0.001) accesses, and higher for jugular than for subclavian access (7.65 versus 1.57, p < 0.001). CRBSI incidence density was statistically higher for femoral than for jugular (8.34 versus 2.99, p = 0.002) and subclavian (8.34 versus 0.97, p < 0.001) accesses, and higher for jugular than for subclavian access (2.99 versus 0.97, p = 0.005). 2

Experimental-Tx 293 patients To compare mechanical, infectious, and thrombotic complications of femoral and subclavian venous catheterization. Femoral catheterization was associated with a higher incidence rate of overall infectious complications (19.8% vs 4.5%; P<.001; incidence density of 20 vs 3.7 per 1000 catheter-days) and of major infectious complications (clinical sepsis with or without bloodstream infection, 4.4% vs 1.5%; P =.07; incidence density of 4.5 vs 1.2 per 1000 catheter-days), as well as of overall thrombotic complications (21.5% vs 1.9%; P<.001) and complete thrombosis of the vessel (6% vs 0%; P =.01); rates of overall and major mechanical complications were similar between the 2 groups (17.3% vs 18.8 %; P =.74 and 1.4% vs 2.8%; P =.44, respectively). Risk factors for mechanical complications were duration of insertion (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.03-1.08 per additional minute; P<.001); insertion in 2 of the centers (OR, 4.52; 95% CI, 1.81-11.23; P =.001); and insertion during the night (OR, 2.06; 95% CI, 1.04-4.08; P =.03). The only factor associated with infectious complications was femoral catheterization (hazard ratio [HR], 4.83; 95% CI, 1.96-11.93; P<.001); antibiotic administration via the catheter decreased risk of infectious complications (HR, 0.41; 95% CI, 0.18-0.93; P =.03). Femoral catheterization was the only risk factor for thrombotic complications (OR, 14.42; 95% CI, 3.33-62.57; P<.001). 1

Crit Care Med. 1995;23(1):52-59. Experimental-Tx 45 patients To determine the frequency of central venous catheter-induced deep vein thrombosis of the femoral vein. Of the 21 patients randomized to upper access sites, none developed positive or nondiagnostic duplex ultrasound examinations. Six (25%) of 24 patients randomized to the femoral access site developed lower extremity deep vein thrombosis (p = .02). In addition, seven (29%) patients randomized to the lower access site sustained non-diagnostic ultrasound examinations. A total of 13 (54%) of 24 patients from the lower access group developed abnormal ultrasound examinations (p < .001). Age, duration of catheterization, coagulation profile, deep vein thrombosis prophylaxis, and Acute Physiology and Chronic Health Evaluation II scores were similar between the upper and lower access groups. 1

Meta-analysis 4 studies; 1,513 participants To establish whether the jugular, subclavian or femoral CVA routes resulted in a lower incidence of venous thrombosis, venous stenosis or infections related to CVA devices in adult patients, and to assess whether the jugular, subclavian or femoral CVA routes influenced the incidence of catheter-related mechanical complications in adult patients; and the reasons why patients left the studies early. We identified 5854 citations from the initial search strategy; 28 references were then identified as potentially relevant. Of these, we Included four studies with data from 1513 participants. We undertook a priori subgroup analysis according to the duration of catheterization, short-term (< one month) and long-term (> one month) defined according to the Food and Drug Administration (FDA).No randomized controlled trial (RCT) was found comparing all three CVA routes and reporting the complications of venous stenosis.Regarding internal jugular versus subclavian CVA routes, the evidence was moderate and applicable for long-term catheterization in cancer patients. Subclavian and internal jugular CVA routes had similar risks for catheter-related complications. Regarding femoral versus subclavian CVA routes, the evidence was high and applicable for short-term catheterization in critically ill patients. Subclavian CVA routes were preferable to femoral CVA routes in short-term catheterization because femoral CVA routes were associated with higher risks of catheter colonization (14.18% or 19/134 versus 2.21% or 3/136) (n = 270, one RCT, RR 6.43, 95% CI 1.95 to 21.21) and thrombotic complications (21.55% or 25/116 versus 1.87% or 2/107) (n = 223, one RCT, RR 11.53, 95% CI 2.80 to 47.52) than with subclavian CVA routes. Regarding femoral versus internal jugular routes, the evidence was moderate and applicable for short-term haemodialysis catheterization in critically ill patients. No significant differences were found between femoral and internal jugular CVA routes in catheter colonization, catheter-related bloodstream infection (CRBSI) and thrombotic complications, but fewer mechanical complications occurred in femoral CVA routes (4.86% or 18/370 versus 9.56% or 35/366) (n = 736, one RCT, RR 0.51, 95% CI 0.29 to 0.88).

Experimental-Tx 3,471 catheters in 3,027 patients To evaluate the risk of catheter-related bloodstream infection or symptomatic catheter-related deep-vein thrombosis in adult patients who had been admitted to an intensive care unit (ICU). A total of 3471 catheters were inserted in 3027 patients. In the three-choice comparison, there were 8, 20, and 22 primary outcome events in the subclavian, jugular, and femoral groups, respectively (1.5, 3.6, and 4.6 per 1000 catheter-days; P=0.02). In pairwise comparisons, the risk of the primary outcome was significantly higher in the femoral group than in the subclavian group (hazard ratio, 3.5; 95% confidence interval [CI], 1.5 to 7.8; P=0.003) and in the jugular group than in the subclavian group (hazard ratio, 2.1; 95% CI, 1.0 to 4.3; P=0.04), whereas the risk in the femoral group was similar to that in the jugular group (hazard ratio, 1.3; 95% CI, 0.8 to 2.1; P=0.30). In the three-choice comparison, pneumothorax requiring chest-tube insertion occurred in association with 13 (1.5%) of the subclavian-vein insertions and 4 (0.5%) of the jugular-vein insertions. 1

Ann Oncol. 2009;20(5):935-940. Experimental-Tx 401 patients To compare two different percutaneous routes of access to superior vena cava (subclavian and internal jugular) with a surgical cut-down access through the cephalic vein, evaluating early and late complications, including pneumothorax, clinically relevant bleeding, primary malposition, port-related bacteremia, pocket infections, late dislocation, fibrin sleeve formation, malfunction of the device, extravasation, clinically evident and silent venous thrombosis at anytime. Four hundred and one patients (99.9%) were assessable: 132 with the internal jugular, 136 with the subclavian and 133 with the cephalic vein access. The median follow-up was 356.5 days (range 0-1087). No differences were found for early complication rate in the three groups {internal jugular: 0% [95% confidence interval (CI) 0.0% to 2.7%], subclavian: 0% (95% CI 0.0% to 2.7%), cephalic: 1.5% (95% CI 0.1% to 5.3%)}. US-guided subclavian insertion site had significantly lower failures (e.g. failed attempts to place the catheter in agreement with the original arm of randomization, P = 0.001). Infections occurred in one, three and one patients (internal jugular, subclavian and cephalic access, respectively, P = 0.464), whereas venous thrombosis was observed in 15, 8 and 11 patients (P = 0.272). 1

Observational-Tx 253 Hickman catheters in 209 patients To compare the differences in practice and outcome of all radiologically and surgically placed central venous catheters retrospectively over a 2-year period simultaneously, at a single institution. There were 6 (4.5%) primary surgical failures and a further 17 (13%) surgical cases requiring multiple placement attempts.

Catheter or central vein thrombosis occurred in four (3.3%) radiological and five (3.7%) surgical cases. The rate of infection per 1000 catheter-days was 1.9 in radiologically placed catheters and 4.0 in surgically placed ones (p < 0.001). Average catheter life-span was similar for the two placement methods (100 +/- 23 days). 2

Observational-Tx 52 patients with 85 catheters To ascertain the occurrence and severity of this potential complication, i.e. late strictures of the subclavian vein following temporary catheter dialysis via the subclavian or internal jugular route. The two groups were statistically similar with respect to age, sex and race. The subclavian catheters were left in for a mean of 11.5 days (2-22) while the internal jugular ones were inserted for 15.8 days (5-25; p = 0.0015). One hundred percent of the internal jugular patients were free of any venogram abnormalities in their venous access return. In marked contrast, 50% of the subclavian sites had mild to severe stricutures with 90% having 70-100% occlusion of the subclavian vein. Six patients had bilateral severe strictures. 2

Experimental-Tx 24 patients; 25 catheters To evaluate interventional radiologic placement of tunneled hemodialysis catheters in small thyrocervical collateral veins or in occluded veins in the neck or chest in patients with limited venous access. Technical success was achieved in 22 (88%) of 25 procedures (one patient underwent two procedures). All catheters functioned immediately after placement. There were two procedural complications: a vasovagal episode requiring intravenously administered atropine sulfate and an episode of respiratory distress requiring intubation. There were no instances of pneumothorax, nerve injury, or bleeding complications. Catheter malfunction requiring exchange occurred at a rate of 0.67 per 100 catheter days. Infection requiring catheter removal occurred at a rate of 0.06 per 100 catheter days. Primary patency was 90% at 1 month, 71% at 6 months, and 25% at 12 months. Secondary patency was 100% at 6 months and 70% at 12 months. 2

Experimental-Tx 17 double-lumen hemodialysis catheters in 12 patients To evaluate the percutaneous translumbar approach for long-term hemodialysis catheter access. Catheter placement was successful in all patients. Adequate flow rates were obtained. Seven episodes of thrombosis-related access failure occurred (0.33 episodes/100 days at risk). Two catheters were removed and five catheters were managed with urokinase infusion. Six episodes of infection occurred (0.28 episodes/100 days at risk). Four required catheter removal. Two catheters were removed after defects developed in the catheter. Five catheters were removed electively because catheter hemodialysis was discontinued. Four catheters remained in place. Cumulative patency was 52% at 6 months and 17% at 12 months. 2

Observational-Tx 36 catheters in 12 patients To examine our experience, including clinical follow-up with transhepatic hemodialysis catheters in patients in whom more traditional venous access sites have been exhausted. Twenty-one catheters were replaced or removed because of catheter thrombosis, yielding a catheter thrombosis rate of 2.40 per 100 catheter-days. The line sepsis rate was 0.22 per 100 catheter-days. Poor patency rates were seen because of a high rate of late thrombosis. 2

J Acquir Immune Defic Syndr. 1990;3(4):335-342. Observational-Tx 299 patients - 54 AIDS, 102 non-AIDS immunodeficiencies, 98 immunocompetent To evaluate the risk of catheter infection in patients with acquired immune deficiency syndrome (AIDS). The rate of infection per 1,000 catheter days was 2.02, 0.41 (p less than 0.002), and 0.23 (p less than 0.002), respectively. Gram-positive cocci were the predominant isolate. Previous catheter infection and advanced AIDS (as determined by positive p24 antigen and low CD4+ number) were associated with increased risk of infection. Exit, tunnel, and fungal infections required catheter removal. The risk of infection and management were similar in Hickman and Port-a-cath catheters. The mortality was extremely low in all groups. However, the risk of infection associated with indwelling catheters was significantly higher in AIDS patients compared to patients with other immunodeficiencies. 2

Scand J Infect Dis. 1993;25(3):357-364. Observational-Tx 97 episodes To detect factors, if any, that would favour keeping or removing the central venous line during a septic episode. The need for catheter removal during a febrile infection was 0.32/1000 catheter days, and the documented sepsis rate was 0.59/1000 catheter days. Our data indicate that 94% of episodes of fever and neutropenia in total, 78% of documented septicemias, and 97% of fevers of unknown origin were curable with broad-coverage antimicrobial therapy without removing the central venous line. 2

Observational-Tx 966 CVADs (mostly venous ports) in 933 patients To describe the epidemiology of infections related to the use of implantable central venous access devices (CVADs) in cancer patients and to evaluate measures aimed at reducing the rates of such infections. During the study period, 966 CVADs (mostly venous ports) were implanted in 933 patients, for a combined total of 243,792 catheter-days. We identified 184 episodes of infection: 154 (84%) were bloodstream infections, 21 (11%) were pocket infections, and 9 (5%) were surgical site infections. During the study period, the rate of CVAD-related infection dropped from 2.2 to 0.24 per 1,000 catheter-days ([Formula: see text]). Multivariate analysis revealed that relevant risk factors for such infection include surgical reintervention, implantation in a neutropenic patient, in-hospital implantation, use of a cuffed catheter, and nonchemotherapy indication for catheter use. 2

Eur J Radiol. 1995;20(2):108-111. Observational-Tx 57 patients To evaluate the incidence of axillary-subclavian vein thrombosis in cancer patients with CVC and without clinical symptoms of venous obstruction. Different degrees of incomplete thrombosis were found in 26 patients (45.5%) and complete thrombosis, clinically silent, was found in six patients (10.5%). A fibrin sleeve around the CVC was radiologically demonstrated in 45 (78%) patients, 21 of them (46%) with negative standard venogram. Only in four patients there was no evidence of fibrin sleeve or parietal thrombosis. There were no significant differences between patients with long-term and short-term CVCs. 2

Experimental-Tx 82 patients To determine whether very low doses of warfarin are useful in thrombosis prophylaxis in patients with central venous catheters. One hundred twenty-one patients entered the study, and 82 patients completed the study. Of 42 patients completing the study while receiving warfarin, 4 had venogram-proven thrombosis. All 4 had symptoms from thrombosis. Of 40 patients completing the study while not receiving warfarin, 15 had venogram-proven thrombosis, and 10 had symptoms from thrombosis (P less than 0.001). There were no measurable changes in the coagulation values assayed due to this warfarin dose, except in occasional patients who had become anorectic because of their disease or chemotherapy. 1

Observational-Tx 95 patients To evaluate prevalence, timing and evolution of thrombosis, and identify involved veins and risk factors in cancer patients (pts) undergoing percutaneous subclavian central venous catheterization (CVC) for chemotherapy, parenteral nutrition or both. CRCVT was observed in 63/95 (66%) pts. At day 8, 30 and 105 (representing the median days in which first, second and last P were performed) CRCVT was evidenced in 64%, 65% and 66% of the pts, respectively. Thrombus grading did not differ among first, second and last P. CRCVT was symptomatic in 4/63 (6%) pts. Thrombosis prevalence was higher in subclavian (97%) with respect to innominate (60%) or cava (13%) veins (p < 0.001). Thrombosis was higher in left subclavian catheters (14/16; 87.5%) than in right ones (49/79; 62%), p < 0.01. No associations were established between CRCVT and other investigated parameters. 1

Experimental-Tx 32 patients To investigate the effectiveness of low doses of Fragmin in preventing catheter-related DVT; and to try to confirm if patients with high platelet counts are at a higher risk to develop subclavian DVT, as previously suggested. DVT developed in 1/16 patients (6%) taking Fragmin and 8/13 patients (62%) without prophylaxis (Relative Risk 6.75; 95% CI: 1.05-43.58; p = 0.002, Fisher exact test). No bleeding complications had developed. As for prediction of DVT, there was a tendency towards a higher platelet count in those patients who subsequently developed DVT, but differences failed to reach any statistical significance (286 +/- 145 vs 207 +/- 81 x 10(9)/1; p = 0.067). 1

Thrombosis was observed in 34 (23%) of 145 patients. Thrombosis did not cause any signs or symptoms in 31 patients but resulted in overt clinical symptoms in 3 patients. The absence of anticoagulant therapy, use of hormone therapy, and a personal history of venous thrombosis were associated with an increased risk of thrombosis. The risk of thrombosis increased in the presence of multiple pacemaker leads compared to a single lead. 1

J Thromb Haemost. 2010;8(4):684-692. Review/Other-Dx 17 articles with 793 patients; 2 independent reviewers Systematic review was performed to assess whether the diagnostic accuracy of other tests for clinically suspected UEDVT is high enough to justify their use in clinical practice and to evaluate if any test can replace venography. Sensitivity (95% CI) was 97% (90%–100%) for compression US, 84% (72%–97%) for Doppler US, 91% (85%–97%) for Doppler US with compression, and 85% (72%–99%) for phleboreography. The corresponding summary estimates of specificity were, respectively, 96% (87%–100%), 94% (86%–100%), 93% (80%–100%), and 87% (71%–100%). Clinical findings, a clinical score, D-dimer, MRI, rheography and plethysmography were evaluated in 1 study each, involving a median number of 46 patients (range 21–214). Sensitivity and specificity ranged from 0% to 100% and from 14% to 100%. Methodological limitations, large between-study differences and small sample sizes limit the evidence of tests for clinically suspected UEDVT. Compression US may be an acceptable alternative to venography. The addition of (color) Doppler does not seem to improve the accuracy. Adequately designed studies are warranted to confirm these findings. 4

Review/Other-Tx 7 studies To perform a systematic review of clinical studies that have examined the incidence, clinical features, risk factors and management of post-thrombotic syndrome after UEDVT. Seven studies were reviewed. The frequency of PTS after UEDVT ranges from 7-46% (weighted mean 15%). Residual thrombosis and axillosubclavian vein thrombosis appear to be associated with an increased risk of PTS, whereas catheter-associated UEDVT may be associated with a decreased risk. There is currently no validated, standardized scale to assess upper extremity PTS, and little consensus regarding the optimal management of this condition. Quality of life is impaired in patients with upper extremity PTS, especially after DVT of the dominant arm. 4

Review/Other-Dx 598 patients To analyze the mortality and incidence of PE diagnosed with subclavian/axillary/internal jugular vein thrombosis during an 11-year period at our institution and compare the data to those of patients diagnosed with brachial DVT. Mortality rates at 2 months were 29%, 25%, and 21% for each group, respectively. The number of patients diagnosed with PE by ventilation/perfusion scans in groups I, II, and III, respectively, were 5%, 6.25% and 11.5% (p = 0.13). Furthermore, stratification by risk factors failed to demonstrate factors associated with increased 2-month mortality. Contrary to the initial hypothesis of a relationship between the site of thrombosis and the incidence of PE and mortality, these data demonstrated no statistical differences in mortality or incidence of PE among the groups studied. Additionally, these data suggest that brachial vein thrombosis is a disease process related to comparable associated mortality and morbidity similar to other forms of UEDVT. 4

Circulation. 2004;110(5):566-570. Review/Other-Dx 115 patients To investigate the role of potential risk factors and to evaluate the recurrence rate after a period of anticoagulant therapy in a large series of patients with primary upper-extremity DVT. Recurrent upper-extremity DVT was evaluated prospectively over a median of 5.1 years of follow-up. The adjusted odds ratio for upper-extremity DVT was 6.2 (95% CI 2.5 to 15.7) for factor V Leiden, 5.0 (95% CI 2.0 to 12.2) for prothrombin G20210A, and 4.9 (95% CI 1.1 to 22.0) for the anticoagulant protein deficiencies. Hyperhomocysteinemia and oral contraceptives were not associated with upper-extremity DVT. However, in women with factor V Leiden or prothrombin G20210A who were taking oral contraceptives, the odds ratio for upper-extremity DVT was increased up to 13.6 (95% CI 2.7 to 67.3). The recurrence rate was 4.4% patient-years in patients with thrombophilia and 1.6% patient-years in those without thrombophilia. The hazard ratio for recurrent upper-extremity DVT in patients with thrombophilia compared with those without was 2.7 (95% CI 0.7 to 9.8). 4

Observational-Tx 79 patients To evaluate the prevalence of pulmonary embolism (PE), and to identify clinical variables that would increase the likelihood of developing PE in an individual patient. Thirteen patients were considered to have PE. Sixty-six patients were finally classified as having a normal lung scan, and 7 patients were excluded from the study (because of indeterminate lung scan 6; because of femoropopliteal thrombosis simultaneously present 1). Two out of the 13 patients with PE subsequently died because of recurrent, massive embolism, despite adequate heparin therapy. PE was more commonly present in patients with polyvinyle chloride or polyethylene catheters (10/38, 26%) as compared to patients with either polyurethane or siliconized catheters (3/41, 7%; p < 0.05, Chi-Square test; Odds Ratio = 4.52, 95% CI 1.01-23.07). 1

Review/Other-Tx 512 patients To analyze the demographic characteristics, treatment, and 3-month outcome of all patients with DVT in the arm. Of the 11,564 DVT patients enrolled, 512 patients (4.4%) had arm DVT. They presented less often with clinically overt PE (9.0% vs 29%; odds ratio, 0.24; 95% confidence interval [CI], 0.18 to 0.33) than those with lower-limb DVT, but their 3-month outcome was similar. Of the 512 patients with arm DVT, 196 patients (38%) had cancer and 228 patients (45%) had catheter-related DVT. During follow-up, those with cancer DVT had an increased incidence of major bleeding (4.1% vs 0.9%; odds ratio, 4.4; 95% CI, 1.2 to 21), recurrent venous thromboembolism (6.1% vs 2.8%; odds ratio, 2.2; 95% CI, 0.91 to 5.6; p = 0.04), and death (22% vs 3.5%; odds ratio, 7.8; 95% CI, 4.0 to 16). Thirty patients had the composite event of recurrent DVT, symptomatic PE, or major bleeding. They were significantly older, more often had cancer, and presented more frequently with symptomatic PE on hospital admission. On multivariate analysis, only cancer patients with arm DVT had an increased risk for the composite event (odds ratio, 3.0; 95% CI, 1.4 to 6.4). 4

Experimental-Tx 52 patients To report the results of a prospective investigation in patients with subclavian vein catheters. There were 26 polyvinyl chloride and 26 rubber silicone catheters, which were correctly positioned in the superior vena cava-atrium. Average duration of the intravenous stay was 12.8 days. Asymptomatic thrombosis was venographically demonstrated in 46.1% of the polyvinyl chloride catheters and in 11.5% of the silicone ones (p = 0.005). The average age of catheters with or without thrombosis was 10.8 and 13.8 days, respectively. Addition of heparin to the infusate (1 U/ml) did not reduce the thrombosis rate in polyvinyl chloride or in silicone catheters, but risk of thrombosis was significantly higher (p = 0.03) in polyvinyl chloride catheters without heparin in comparison to the silicone ones. Osmolarity of the infusional fluid, manipulation during the cannulation, colonization of the catheter tip, and duration of the intravenous stay of the catheter apparently did not influence the rate of thrombosis. 2

Among 85 children, 29 (34%) had VTE; 28 VTEs appeared in the upper venous system, and 1 was sinovenous thrombosis. Left-sided CVL (odds ratio [OR], 2.5; 95% confidence interval, 1.0-6.4; P =.048), subclavian CVL (OR, 3.1; 95% CI, 1.2-8.5; P =.025), and percutaneous CVL insertion (OR, 3.5; 95% CI, 1.3-9.2; P =.011) were associated with an increased incidence of VTE. Interaction occurred between CVL vein location and insertion technique. Subclavian vein CVL inserted percutaneously had an increased incidence (54%) of VTE compared with any other combination (P =.07). 1

Observational-Tx 472 patients To analyze factors affecting patency and complications of first TDCs placed in a large cohort of incident hemodialysis recipients. The median patency of all TDCs was 202 days. Left-sided placement of TDCs was the only variable associated with inferior TDC patency (hazard ratio, 1.98; 95% confidence interval, 1.39-2.81; P < .0001). The 6-month TDC patency rate was 37% for left internal jugular vein (LIJV) catheters, versus 54% for right internal jugular vein (RIJV) catheters. The 1-year patency rate was 6% for LIJV catheters, versus 35% for RIJV catheters. Catheter patency was not associated with patient age, sex, race, hypertension, diabetes, coronary artery disease, peripheral vascular disease, cerebrovascular disease, or heart failure. The median time to the first episode of CRB was 163 days. None of the clinical variables was associated with TDC infection. 3

Data of 239 patients were analyzed (125 of CVC group, 114 of PICC group). A total of 2,747 CVC-days and 4,024 PICC-days of observation were included. Patient characteristics were comparable between groups. Patients with PICC had a significantly higher incidence rate of deep venous thrombosis (DVT) than patients with CVC (27.2 vs. 9.6%, P = 0.0012). The rate of DVT/1,000 catheter days was 4.4 for CVCs and 7.7 for PICCs. Eighty percent of DVTs occurred within 2 weeks after insertion. Binary logistic analysis showed a two-fold increased risk for women and a three-fold increased risk when using the left basilic vein in the PICC group. 1

81. Hind D, Calvert N, McWilliams R, et al. Ultrasonic locating devices for central venous cannulation: meta-analysis. BMJ. 2003;327(7411):361. Meta-analysis 1,646 participants; 18 trials To assess the evidence for the clinical effectiveness of ultrasound guided central venous cannulation. 18 trials (1646 participants) were identified. Compared with the landmark method, real time two dimensional ultrasound guidance for cannulating the internal jugular vein in adults was associated with a significantly lower failure rate both overall (relative risk 0.14, 95% confidence interval 0.06 to 0.33) and on the first attempt (0.59, 0.39 to 0.88). Limited evidence favoured two dimensional ultrasound guidance for subclavian vein and femoral vein procedures in adults (0.14, 0.04 to 0.57 and 0.29, 0.07 to 1.21, respectively). Three studies in infants confirmed a higher success rate with two dimensional ultrasonography for internal jugular procedures (0.15, 0.03 to 0.64). Doppler guided cannulation of the internal jugular vein in adults was more successful than the landmark method (0.39, 0.17 to 0.92), but the landmark method was more successful for subclavian vein procedures (1.48, 1.03 to 2.14). No significant difference was found between these techniques for cannulation of the internal jugular vein in infants. An indirect comparison of relative risks suggested that two dimensional ultrasonography would be more successful than Doppler guidance for subclavian vein procedures in adults (0.09, 0.02 to 0.38). M

Review/Other-Tx N/A To compare the economics of using two-dimensional ultrasound locating devices and more traditional landmark methods for central venous cannulation in the National Health Service (NHS). The marginal economic cost of using ultrasound for central venous cannulation was less than 10 pounds sterling per procedure, assuming that a machine is used for 15 procedures each week. The base case scenario implied that 2000 pounds sterling worth of resource savings result for every 1000 procedures undertaken and 90 avoided complications. Sensitivity analysis indicated that the results of modelling appear robust to the central assumptions used. 4

Review/Other-Tx N/A To review the current literature on long-term complications of venous port systems, focusing on infection and thrombosis as well as on their routine maintenance in follow-up care. Sterile precautions are essential when implanting and accessing port systems. Infections must be treated with adequate antimicrobial therapy. Catheter-related thromboembolic complications were found at a rate of 12-64% in retrospective studies. Five current clinical trials investigated the effect of prophylactic anticoagulation with either low molecular weight heparin or warfarin in cancer patients with central venous devices. On the basis of these results, routine anticoagulation cannot be recommended. 4

Observational-Tx 73 patients To demonstrate that a longer interval between maintenance accessions of PACs still may be medically safe, convenient, and more efficient. Compliance with visits for PAC maintenance varied considerably with the individual median accession times varying between 28 and 262 days with an overall median of 42 days. The individual means ranged from 29.5 to 244 days with an overall mean of 53.6 days. Seven patients in the group had episodes where the provider was unable to draw blood from the port during routine accession. The average intervals between accessions for each of these patients ranged from 38 to 244 days. The average intervals of accession among those patients who had no blood return during PAC accession was 79 days, versus 63 days for those without any difficulty. The difference was not statistically significant (p>0.05). 2

Experimental-Tx 225 patients To determine whether substituting rt-PA (1 mg in each lumen) for heparin once a week as a catheter locking solution, as compared with using heparin three times a week, would decrease the incidence of catheter malfunction and bacteremia. A catheter malfunction occurred in 40 of the 115 patients assigned to heparin only (34.8%) and 22 of the 110 patients assigned to rt-PA (20.0%)--an increase in the risk of catheter malfunction by a factor of almost 2 among patients treated with heparin only as compared with those treated with rt-PA once weekly (hazard ratio, 1.91; 95% confidence interval [CI], 1.13 to 3.22; P = 0.02). Catheter-related bacteremia occurred in 15 patients (13.0%) assigned to heparin only, as compared with 5 (4.5%) assigned to rt-PA (corresponding to 1.37 and 0.40 episodes per 1000 patient-days in the heparin and rt-PA groups, respectively; P = 0.02). The risk of bacteremia from any cause was higher in the heparin group than in the rt-PA group by a factor of 3 (hazard ratio, 3.30; 95% CI, 1.18 to 9.22; P = 0.02). The risk of adverse events, including bleeding, was similar in the two groups. 1

Clin J Am Soc Nephrol. 2014;9(7):1232-1239. Observational-Tx 555 patients To evaluate the impact of a prophylactic antibiotic lock solution on the incidence of catheter-related bloodstream infection and mortality. The study population (n=555 and 1350 catheters) had a median age of 62 years (interquartile range=41-83 years), with 50% men and 71% black. There were 427 patients evaluable in the heparin period (84,326 days) and 322 patients evaluable in the antibiotic lock period (71,192 days). Catheter-related bloodstream infection in the antibiotic lock period (0.45/1000 catheter days) was 73% lower than the heparin period (1.68/1000 catheter days; P=0.001). Antibiotic lock use was associated with a decreased risk of catheter-related bloodstream infection compared with heparin (risk ratio, 0.23; 95% confidence interval, 0.13 to 0.38 after multivariate adjustment). Cox proportional hazards modeling found that antibiotic lock was associated with a reduction in mortality (hazard ratio, 0.36; 95% confidence interval, 0.22 to 0.58 in unadjusted analyses; hazard ratio, 0.32; 95% confidence interval, 0.14 to 0.75 after multivariate adjustment). The rate of gentamicin-resistant organisms decreased (0.40/1000 person-years to 0.22/1000 person-years) in the antibiotic lock period (P=0.01). 1

Meta-analysis 13 RCTs; 1,770 patients and 221,064 catheter days To assess whether citrate locks are superior to heparin locks in the maintenance of catheter patency and the prevention of CRIs in patients receiving hemodialysis. Primary outcomes include catheter-related bloodstream infection (CRBSI), exit-site infection, catheter removal for poor flow, and thrombolytic treatment. RESULTS: 13 randomized controlled trials (1,770 patients, 221,064 catheter-days) met the inclusion criteria. Pooled analyses found that citrate locks could significantly reduce the incidence of CRBSI (risk ratio [RR], 0.39; 95% CI, 0.27-0.56; P < 0.001). Subgroup analysis showed that antimicrobial-containing citrate locks (citrate + gentamicin, citrate + taurolidine, and citrate + methylene blue + methylparaben + propylparaben) were superior to heparin locks in the prevention of CRBSI (P < 0.001, P = 0.003, and P = 0.008, respectively), whereas citrate alone failed to show a similar advantage (P = 0.2). Low- (1.04%-4%) to moderate-concentration (4.6%-7%) citrate locks were associated with decreased CRBSI incidence (P < 0.001 and P = 0.003, respectively), but patients receiving high-concentration (30%-46.7%) citrate and heparin locks had similar incidences (P = 0.3). The incidence of bleeding episodes (RR, 0.48; 95% CI, 0.30-0.76; P = 0.002) was significantly lower in patients receiving citrate locks, whereas both groups were similar in terms of exit-site infection (P = 0.2), catheter removal for poor flow (P = 0.9), thrombolytic treatment (P = 0.8), all-cause death (P = 0.3), catheter thrombosis (P = 0.9), mean catheter duration (P = 0.2), CRBSI-free catheter survival (P = 0.2), and catheter-related readmission (P = 0.5).

J Thromb Haemost. 2007;5(12):2552-2554. Meta-analysis 7 studies; 2,131 patients To expand and update the literature by incorporating data from two further multi-center, randomized trials. The pooled RR of symptomatic catheter-related thrombosis from the seven RCTs that assessed thromboprophylaxis was 0.71 (95% CI 0.42–1.20; Fig. 1). The pooled estimates of thromboprophylaxis with LMWH and warfarin were 0.43 (95% CI 0.12–1.56) and 0.82 (95% CI 0.46–1.47), respectively. Six out of seven studies reported on overall mortality. No statistically significant mortality benefit was found with either LMWH (RR 1.51; 95% CI 0.49–4.70) or warfarin (RR 0.95; 95% CI 0.62–1.46). Two studies reported on major bleeding, with Karthaus et al. [11] reporting a RR of 0.49 (95% CI 0.03– 7.83) and Couban et al. [9] reporting a RR of 0.14 (95% CI 0.001–2.63). Minor bleeding was not more frequent in patients given thromboprophylaxis with either LMWH (pooled RR 1.32; 95% CI 0.87–2.02) or low-dose warfarin (pooled RR 0.93; 95% CI 0.31–2.77). Heterogeneity for all analyses was nonsignificant or low to moderate, as demonstrated by the chi-square and I 2 tests. M

Experimental-Tx 160 patients To investigate whether three times weekly urokinase rinsing of CVC reduces the incidence or severity of CVC-related infections by CoNS in patients undergoing intensive cytotoxic treatment for hematologic malignancies. The percentage of patients with at least one positive culture with CoNS was lower in patients receiving urokinase compared with patients receiving placebo (26% v 42%, respectively; relative risk [RR] = 0.61; 95% CI, 0.39 to 0.94). Major CVC-related CoNS infection occurred less frequently in patients receiving urokinase versus placebo (1.2% v 14.1%, respectively; RR = 0.09; 95% CI, 0.01 to 0.50). Secondary complications, including CVC-related thrombosis, were observed less frequently in the urokinase group compared with the placebo group (1.3% v 9.0%, respectively; RR = 0.14; 95% CI, 0.02 to 0.82). No severe bleeding complications attributable to urokinase were observed. 1

Experimental-Tx 1,590 patients To assess whether warfarin reduces catheter-related thrombosis compared with no warfarin and whether the dose of warfarin determines the thromboprophylactic effect. Compared with no warfarin (n=404), warfarin (n=408; 324 [79%] on fixed-dose and 84 [21%] on dose-adjusted) did not reduce the rate of catheter-related thromboses (24 [6%] vs 24 [6%]; relative risk 0.99, 95% CI 0.57-1.72, p=0.98). However, compared with fixed-dose warfarin (n=471), dose-adjusted warfarin (n=473) was superior in the prevention of catheter-related thromboses (13 [3%] vs 34 [7%]; 0.38, 0.20-0.71, p=0.002). Major bleeding events were rare; an excess was noted with warfarin compared with no warfarin (7 vs 1, p=0.07) and with dose-adjusted warfarin compared with fixed-dose warfarin (16 vs 7, p=0.09). A combined endpoint of thromboses and major bleeding showed no difference between comparisons. We did not note a survival benefit in either comparison. 1

Experimental-Tx 1,064 patients To analyze the safety and efficacy of alteplase after administration of a maximum of two 2-mg/2-mL doses to thrombosed CVADs. A total of 1,064 patients (465 men, 599 women; mean age, 50.7 y; range, 2-91 y) with dysfunctional catheters were treated. After alteplase administration, function was restored in 798 patients (75.0%; 95% CI: 72.3%, 77.6%) after one dose and 905 (85.1%; 95% CI: 82.8%, 87.2%) after two doses. Efficacy rates were similar among catheter types (single-, double-, and triple-lumen catheters, and ports). Serious adverse events monitored within 30 days of treatment included ICH (0.0%), embolic events (0.0%), gastrointestinal bleeding (0.3%), thrombosis (0.3%), and sepsis (0.4%). One event (fever) was attributed to the study drug. Efficacy was independent of age, sex, body weight, and catheter type. 1

Eur J Radiol. 2004;52(3):293-299. Observational-Tx 57 patients To determine the incidence of pericatheter sleeve formation, thrombus formation, and stenosis of the central veins in hemodialysis patients with temporary catheters. The catheter location was right internal jugular vein (IJV) in 26 cases, right subclavian vein (SCV) in 27 cases, left IJV in 1 case, and left SCV in 3 cases. Thirty-two patients (56%) had had only one temporary catheter and the rest had had more than one inserted. The mean dwell time for the catheters was 21 days (range 7-59 days). A pericatheter sleeve was detected on venography in 32 (56%) patients and thrombus formation was noted in 16 patients (28%). A total of 41 patients (72%) exhibited pericatheter sleeve and/or thrombus formation. While 19 of the 32 patients (59%) without previous catheterization had a sleeve around the catheter, only 13 (52%) of 25 patients who had had multiple catheters inserted had a sleeve (P > 0.005). Of the eight patients (14%) with BCV stenosis, two had >50% stenosis. Only one patient (2%) had mild stenosis of the SVC. Three patients out of 15 (20%) who had diagnostic venography for the IJV had severe stenosis of the vein. Pericatheter sleeve formation was more frequent in women (P < 0.005). However, there were no statistical differences with respect to pericatheter sleeve formation, luminal filling defect and BCV stenosis when patients were grouped according to age, dwell time of the catheter, number of catheters inserted, and diameter of the SVC. Forty-two of the fifty-seven patients had had only right IJV (n =16) or right SCV (n = 26) catheters. There were no differences between these groups with respect to rates of pericatheter sleeve formation, thrombus formation, or BCV stenosis. 1

J Vasc Interv Radiol. 2006;17(6):1011-1015. Observational-Tx 66 procedures in 45 patients To compare median patency times after treatment of malfunctioning tunneled hemodialysis catheters by one of three techniques: over-the-wire catheter exchange (CE), fibrin sheath stripping (FSS) from a femoral vein approach, and over-the-wire catheter removal with balloon dilation of fibrin sheath (DFS) followed by catheter replacement with use of the same tract. No significant differences in baseline parameters were identified among the three groups (P>.05). Mean follow-up duration (67+/-89 days; range, 0-398 d) was similar among the three groups. The immediate technical success rate was 100%, and there were no complications. Cumulative catheter patency rates were 73% (CE), 72% (FSS), and 65% (DFS) at 1 month; 43% (CE), 60% (FSS), and 39% (DFS) at 3 months; and 28% (CE), 45% (FSS), and 39% (DFS) at 6 months. Median duration of patency was similar among groups (P=.60). 2

International clinical practice guidelines for the treatment and prophylaxis of thrombosis associated with central venous catheters in patients with cancer. [Review]. J Thromb Haemost. 11(1):71-80, 2013 Jan. Review/Other-Tx N/A To establish common international Good Clinical Practices Guidelines (GCPG) for the management of CRT in cancer patients. For the treatment of established CRT in cancer patients, we found no prospective randomized studies, two non-randomized prospective studies and one retrospective study examining the efficacy and safety of low-molecular-weight heparin (LMWH) plus vitamin K antagonists (VKAs). One retrospective study evaluated the benefit of CVC removal and two small retrospective studies were on thrombolytic drugs. For the treatment of symptomatic CRT, anticoagulant treatment (AC) is recommended for a minimum of 3 months; in this setting, LMWHs are suggested. VKAs can also be used, in the absence of direct comparisons of these two types of anticoagulants in this setting [Guidance]. The CVC can be kept in place if it is functional, well-positioned and non-infected and there is good resolution under close surveillance; whether the CVC is kept or removed, no standard approach in terms of AC duration has been established [Guidance]. For the prophylaxis of CRT in cancer patients, we found six randomized studies investigating the efficacy and safety of VKA vs. placebo or no treatment, one on the efficacy and safety of unfractionnated heparin, six on the value of LMWH, one double-blind randomized and one non randomized study on thrombolytic drugs and six meta-analyses of AC and CVC thromboprophylaxis. Type of catheter (open-ended like the Hickman((R)) catheter vs. closed-ended catheter with a valve like the Groshong((R)) catheter), its position (above, below or at the junction of the superior vena cava and the right atrium) and method of placement may influence the onset of CRT on the basis of six retrospective trials, four prospective non-randomized trials, three randomized trials and one meta-analysis. In light of these data: use of AC for routine prophylaxis of CRT is not recommended [1A]; a CVC should be inserted on the right side, in the jugular vein, and distal extremity of the CVC should be located at the junction of the superior vena cava and the right atrium [1A]. 4

Thromb Res. 2002;108(5-6):279-285. Observational-Tx 95 patients To investigate long-term clinical and morphological outcome of patients with subclavian-axillary vein thrombosis treated with systemic thrombolysis compared to anticoagulation in a retrospective, nonrandomised study. Primary technical success rate of the systemic thrombolysis was 88% (n=29) with seven peri-intervention bleeding complications (21%). No complication was observed in patients with anticoagulation only (p<0.0001). At the time of follow-up, duplex sonography showed a thrombotic subclavian vein in 40 of 83 patients (48%), but only 9 of 95 patients (10%) had a symptomatic upper extremity post-thrombotic syndrome. Patients with systemic thrombolysis exhibited a 60% adjusted reduced risk for a thrombotic subclavian vein at the time of follow-up compared to patients with anticoagulation only (95% CI: 0.2 to 0.9, p=0.03). However, the frequency of symptomatic post-thrombotic syndrome after thrombolysis and anticoagulation was similar (adjusted p=0.6). 2

Observational-Tx 30 patients To report thrombolytic efficacy, complications, and follow-up data on PTS and reocclusion for patients treated with CDT for UEDVT at the University Hospital of North Norway and Rikshospitalet University Hospital, Oslo, between 2002 and 2007. UEDVT was unprovoked in 11 (37%) cases and effort related in 9 (30%) cases. The median duration of symptoms prior to CDT was 7.0 days (range, 1-30); median duration of thrombolysis treatment, 70 h (range, 24-264 h); and the median amount of rt-PA infused during CDT, 52 mg (range, 19-225 mg). Major bleeding was registered in three (9%) patients, and CDT was stopped prematurely in three patients due to local hematoma. No intracerebral bleeding, clinical pulmonary embolism, or deaths occurred during treatment. Grade II (>50%) or III (>90%) lysis was present in 29 patients (97%) at the end of CDT. Bleeding complications increased by each day of delay from the debut of symptoms to the start of treatment (OR, 1.20; 95% CI, 1.01-1.42). At follow-up (n = 29; median, 21 months; range, 5-58 months), 11 (38%) patients had occluded veins, whereas 18 (62%) had patent veins. However, stenosis of varying severity was present in eight of those with a patent vein. No patients had severe PTS, whereas six (21%) experienced mild PTS. 2

A total of 21 publications were identified that reported 209 SVC filters and documented eight major filter-related complications (3.8%), including four cardiac tamponades, two aortic perforations, and one recurrent pneumothorax. The in-hospital or 1-month mortality rate was 43.1%. Twenty-eight additional publications were identified that reported 3,747 cases of UEDVT. The rates of PE and associated mortality were 5.6% and 0.7%, respectively. Studies imaging both upper and lower extremities found deep vein thrombus 14.7 times more likely to occur in the lower extremities and the rate of PE from a lower-extremity thrombus to be 25.1%. 4

Review/Other-Tx 154 patients To review our experience with 154 patients who received SVC filter for UEDVT. There were 69 males and 85 females with a mean age of 73.6 years (range, 16-96 years; +/-15.3 [SD] years). Follow-up ranged from 1 day to 3750 days (256.3 +/- 576 days [mean +/- SD]) and 5 patients were lost to follow-up. Of the 154 patients, 58 survived longer than 60 days with mean follow-up of 628.4 days. All SVC filters (TrapEase, n = 38; Greenfield, n = 116) were successfully deployed in the 154 patients. During the follow-up, 114 (74.0% mortality) of the patients died of chronic illness or from cancer complications. There were three cases of pericardial tamponade (1.9%), and one case of misplaced filter in innominate vein. There were no known cases of symptomatic pulmonary embolism, caval occlusion, pneumothorax, or filter migration. SVC filter placement is associated with a low incidence of complications with long-term follow-up. 4

Clin Microbiol Infect. 2004;10(9):838-842. Review/Other-Tx 151 hospitals To obtain general general information on the microbiology workload and techniques used for IV-CRI diagnosis in Europe, as well as the aetiology and antimicrobial susceptibility patterns of pathogens causing intravenous catheter colonisation. Overall, EU centres received significantly more catheter tip samples/1,000 admissions and had a significantly higher rate of 'positivity' (p < 0.0001) than non-EU centres. Of the institutions surveyed, 11.4% (7.2% in EU countries and 23.7% in non-EU countries; p 0.04) used only qualitative techniques for catheter tip sample processing. On the day of the study, 167 microorganisms were recovered from significant catheter tip cultures (122 patients), of which Gram-positive bacteria represented 70.7%, Gram-negative bacteria 22.2%, and yeasts 7.2%. The five most common microorganisms were coagulase-negative staphylococci, Staphylococcus aureus, Candida spp., Enterococcus spp. and Pseudomonas spp. Overall, 19% of catheter tip cultures were polymicrobial. In the case of S. aureus, 40% of isolates were resistant to oxacillin, as were 63.4% of coagulase-negative staphylococcus isolates. Of 37 Gram-negative isolates, 35% were resistant to cefotaxime, 31% to ceftazidime, and 27% to ciprofloxacin. Imipenem and cefepime had the lowest reported rates of resistance (11%). 4

Of the CVCs surveyed, 1.6% [95% confidence interval (CI) 1.2-2.0] resulted in CR-BSI, representing 2.0/1000 CVC-days (95% CI 1.6-2.6). Multi-variate analysis revealed that the length of ICU stay prior to CVC insertion, insertion in the jugular or femoral vein, and use of the CVC to deliver total parenteral nutrition increased the risk of CR-BSI, whereas use of the CVC to deliver antibiotics decreased the risk of CR-BSI. 2

Observational-Tx 977 patients To evaluate over a 24-month period the association between risk of BSI and duration of AP use in comparison with the use of a central venous line (CL). BSIs occurred in 81 patients with an AP, for a BSI rate of 2.81 cases per 1,000 days of use. Among the 896 patients with a CL, the BSI rate was 5.60 cases per 1,000 days of use. The ROC analysis found a cutoff time of 33 days for APs (median days of use, 48) and 10 days for CLs (median days of use, 20.5). For the total 22,481 days of use, the odds ratio between APs and CLs with respect to BSI was 0.556 (95% confidence interval [CI], 0.256-1.208; P = .138). Days of use beyond the cutoff had an odds ratio of 2.867 (95% CI, 1.823-4.507; P < .001). Among the risk factors, preexisting sepsis had an odds ratio of 7.843 (95% CI, 4.666-13.184; P < .001). 3

Observational-Tx 121 patients To compare the rate of CVC and PICC-related infections in long-stay (14 days) SICU patients. There were 13 CVC infections and one PICC infection, resulting in an infection rate of 6.0/1,000 catheter-days for CVCs and 2.2/1,000 for PICCs. Infected and non-infected CVCs were in place a mean of 25 +/- 11 and 16 +/- 9 days, respectively. The infected PICC was in place for 19 days, whereas the remainder of the PICCs were in place a mean of 14 +/- 17 days. Logistic regression demonstrated that line days (duration of catheterization) was the only independent predictor of CVC infection (p = 0.015). 2

Experimental-Tx 836 patients To determine whether patients bathed daily with chlorhexidine gluconate (CHG) have a lower incidence of primary bloodstream infections (BSIs) compared with patients bathed with soap and water. Patients in the CHG intervention arm were significantly less likely to acquire a primary BSI (4.1 vs 10.4 infections per 1000 patient days; incidence difference, 6.3 [95% confidence interval, 1.2-11.0). The incidences of other infections, including clinical sepsis, were similar between the units. Protection against primary BSI by CHG cleansing was apparent after 5 or more days in the MICU. 2

Experimental-Tx 1787 patients To evaluate the effect of source control on patients’ skin colonization by vancomycin-resistant enterococci (VRE), measured the effect on VRE contamination of environmental surfaces and health care workers’ hands, and assessed all patients for VRE acquisition. Compared with soap and water baths, cleansing patients with chlorhexidine-saturated cloths resulted in 2.5 log(10) less colonies of VRE on patients' skin and less VRE contamination of health care workers' hands (risk ratio [RR], 0.6; 95% confidence interval [CI], 0.4-0.8) and environmental surfaces (RR, 0.3; 95% CI, 0.2-0.5). The incidence of VRE acquisition decreased from 26 colonizations per 1000 patient-days to 9 per 1000 patient-days (RR, 0.4; 95% CI, 0.1-0.9). For all measures, effectiveness of cleansing with nonmedicated cloths was similar to that of soap and water baths. 2

To determine whether a sutureless securement device offers an advantage over suture in preventing catheter-related complications. The groups had equivalent demographic characteristics and catheter indications. Average securement time with StatLock was significantly shorter (4.7 minutes vs 2.7 minutes;P <.001). Although StatLock was associated with fewer total complications (42 vs 61), this difference did not achieve significance. However, there were significantly fewer PICC-related bloodstream infections in the StatLock group (2 vs 10; P =.032). One securement-related needle-stick injury was documented during suturing of a PICC. 1

Infect Control Hosp Epidemiol. 2015;36(12):1401-1408. Observational-Tx Not stated. To examine the impact of routine use of a passive disinfection cap for catheter hub decontamination in hematology-oncology patients. Implementation of a passive disinfection cap resulted in a 34% decrease in hospital-wide HA-CLABSI rates (combined P1 and P2 baseline rate of 2.66-1.75 per 1,000 catheter days at the end of the study period). This reduction occurred only among high-risk patients and not among general oncology patients. In addition, the use of the passive disinfection cap resulted in decreases of 63% (HRUs) and 51% (general oncology units) in blood culture contamination, with an estimated reduction of 242 BCCs with CONS. The reductions in HA-CLABSI and BCC correspond to an estimated annual savings of $3.2 million in direct medical costs. 2

Observational-Tx 4,005 patients To compare the incidence, risk factors, and mortality associated with septicemia between incident diabetic and nondiabetic HD patients. Over 7 years, 11.1% of nondiabetic patients and 12.5% of diabetic patients experienced at least one episode of septicemia. Older age and low serum albumin were independent risk factors for septicemia in all patients. In diabetics, white race, peripheral vascular disease, and hemodialyzer reuse, particularly in type 1, were independent risk factors. In nondiabetics, coronary artery disease, cerebrovascular disease, and temporary and permanent catheters were associated with an increased risk. In both groups, patients who experienced an episode of septicemia had twice the risk of death from any cause and an eightfold risk of death from septicemia. 2

Over seven years of follow-up, 11.7% of 4005 HD patients and 9.4% of 913 PD patients had at least one episode of septicemia. Older age and diabetes were independent risk factors for septicemia in all patients. Among HD patients, low serum albumin, temporary vascular access, and dialyzer reuse were also associated with increased risk. Among PD patients, white race and having no health insurance at dialysis initiation were also risk factors. Patients with septicemia had twice the risk of death from any cause and a fivefold to ninefold increased risk of death from septicemia. 2

Observational-Tx 988 adults To determine the current incidence of and risk factors for bacteremia in chronic hemodialysis patients in France. Staphylococcus aureus (n=20) and coagulase-negative staphylococci (n=15) were responsible for most of the 51 bacteremic episodes recorded. The incidence of bacteremia was 0.93 episode per 100 patient-months. Four risk factors for bacteremia were identified: (1) vascular access (catheter versus fistula: RR=7.6; 95% CI, 3.7 to 15.6); (2) history of bacteremia (> or =2 versus no previous episode: RR=7.3; 95% CI, 3.2 to 16.4); (3) immunosuppressive therapy (current versus no: RR=3.0; 95% CI, 1.0 to 6.1); and (4) corpuscular hemoglobin (per 1 g/dl increment: RR=0.7; 95% CI, 0.6 to 0.9). Catheters, especially long-term implanted catheters, were found to be the leading risk factor of bacteremia in chronic hemodialysis patients. There was a trend toward recurrence of bacteremia that was not associated with chronic staphylococcal nasal carriage. Synthetic membranes were not associated with a lower risk of bacteremia in this population of well dialyzed patients, but anemia linked to resistance to erythropoietin appeared to be a possible risk factor for bacteremia. 1

The clinical effectiveness and cost-effectiveness of central venous catheters treated with anti-infective agents in preventing bloodstream infections: a systematic review and economic evaluation. Health Technol Assess. 2008;12(12):iii-iv, xi-xii, 1-154. Meta-analysis 32 trials To assess the clinical effectiveness and cost-effectiveness of central venous catheters (CVCs) treated with anti-infective agents in preventing catheter-related bloodstream infection (CRBSI). A total of 32 trials met the clinical inclusion criteria. Seven different types of AI-CVC were identified, with the most frequently tested being chlorhexidine and silver sulfadiazine (CHSS) (externally treated), CHSS (externally and internally treated) and minocycline rifampicin (internally and externally treated). In general, the trials were of a poor quality in terms of reported methodology, microbiological relevance and control of confounding variables. The pooled result suggests a statistically significant advantage for AI-CVCs in comparison to standard catheters in reducing CRBSI [odds ratio (OR) 0.45, 95% confidence interval (CI) 0.34 to 0.60, 24 studies, I-squared = 0%, fixed effects]. Analysis by subgroups of catheters demonstrates that antibiotic-treated catheters and catheters treated internally and externally decrease CRBSI rates significantly (OR 0.26, 95% CI 0.15 to 0.46, six studies, I-squared = 0%, fixed effects, and OR 0.43, 95% CI 0.26 to 0.70, nine studies, I-squared = 0%, fixed effects, respectively). Catheters treated only externally demonstrate a wider CI and non-significant effect (OR 0.67, 95% CI 0.43 to 1.06, nine studies, I-squared = 0%, fixed effects). A treatment effect was also found for trials with an average duration of between 5 and 12 days, and for the one study with a mean duration of over 20 days. There was a statistically significant treatment effect for both femoral and jugular insertion sites and for those studies reporting a mix of insertion sites. The treatment effect was not observed in trials using exclusively subclavian insertion sites. Of the four trials that compared treated catheters, one reported a benefit of antibiotic-treated catheters over catheters treated externally with CHSS. All three sensitivity analyses testing for study design differences reported a statistically significant treatment effect. The review was limited owing to the quality of the trials included, marked differences in the definitions and methods of diagnosis of CRBSI, and inconsistent reporting of risk factors and patient population factors. Furthermore, two-thirds of trials were commercially funded. The economic performance (cost-effectiveness and potential cost-savings) of using AI-CVCs to reduce the number of CRBSIs in patients requiring a CVC was also reviewed. Results show that the use of AI-CVCs instead of standard CVCs can lead to a reduction in CRBSIs and decreased medical costs. To complement the reviews, a basic decision-analytic model was constructed to explore a range of possible scenarios for the NHS in England and Wales. Results show that for every patient who receives an AI-CVC there is an estimated cost-saving of 138.20 pounds. The multivariate sensitivity analyses estimate potentially large cost-savings, depending on the size of the population, under a wide range of cost and clinical assumptions. However, those considering the purchase of AI-CVCs should ensure that their patient populations and the important characteristics of local clinical practice are indeed similar to those described in this economic evaluation.

Meta-analysis 48 clinical trials (12,828 CVCs) investigating 10 intervention catheters To compare the effectiveness of various catheters for prevention of catheter-related infection and to evaluate whether specific catheters are superior to others for reducing catheter-related infections. For prevention of CVC colonisation, adjusted silver iontophoretic catheters (odds ratio: 0.58; 95% confidence interval: 0.33-0.95), chlorhexidine and silver sulfadiazine catheters (0.49; 0.36-0.64), chlorhexidine and silver sulfadiazine blue plus catheters (0.37; 0.17-0.69), minocycline-rifampicin catheters (0.28; 0.17-0.43) and miconazole-rifampicin catheters (0.11; 0.02-0.33) were associated with a significantly lower rate of catheter colonisation compared with standard catheters. For prevention of CRBSI, adjusted heparin-bonded catheters (0.20; 0.06-0.44) and minocycline-rifampicin catheters (0.18; 0.08-0.34) were associated with a significantly lower rate of CRBSI with standard catheters.

Groups were well matched for all preoperative variables studied, including comorbid conditions. Superficial surgical site infection developed in 5 patients (2.5%) from the antibiotic group and 6 (3%) from the placebo group (P = .75). One from each group developed deep surgical site infection. Both patients were readmitted and underwent repeated debridement, which eventually resulted in port loss in 1 patient. 1

Cochrane Database Syst Rev. 2007(1):CD003295. Meta-analysis 588 patients; 9 trials To determine the efficacy of administering antibiotics prior to insertion of a TCVC with or without vancomycin/heparin flush technique in the first 45 days after insertion of the catheter to prevent Gram-positive catheter-related infections in oncology patients. We included nine trials with a total of 588 patients. Four reported on vancomycin/teicoplanin prior to insertion of the TCVC compared to placebo, and five trials reported on antibiotic flushing combined with heparin, compared to heparin flushing only. The overall effect of administering an antibiotic prior to insertion of the catheter decreases the number of Gram positive TCVC infections (odds ratio [OR] = 0.42, 95% confidence interval (CI) 0.13 to 1.31), this effect is not significant. Flushing the TCVC with antibiotics and heparin proved to be beneficial (OR = 0.43, 95% CI 0.21 to 0.87). For intraluminal colonization the baseline infection rate is 15% which leads to a number needed to treat (NNT) of 13 (95 % CI 5 to 23). M

Experimental-Tx 129 haemodialysis patients; 69 peritoneal dialysis patients To address the issue of prevention of catheter related infection in haemodialysis and peritoneal dialysis patients. In a prospective, randomized, open study of 129 haemodialysis patients, exit site infection and bacteraemia were significantly greater in the untreated group (18.2% each) than the group treated with povidone-iodine (PVP-I) ointment (4.8% each), P < 0.02. In nasal carriers of S. aureus, PVP-I resulted in 100% risk reduction of bacteraemia and exit site infection (P < 0.05) and 70% risk reduction of catheter tip infections (P < 0.05). Preliminary results of an on-going randomized study in patients on intermittent peritoneal dialysis suggest, in the 69 patients so far studied, a reduced S. aureus infection rate in patients who received PVP-I ointment at the catheter exit site (2.9%) compared with the untreated group (8.8%) despite a higher nasal carriage rate in the PVP-I group. Statistical significance has not been demonstrated for these interim results and the study is continuing. 1

Nephrol Dial Transplant. 2002;17(10):1802-1807. Experimental-Tx 50 patients To compare the effect of thrice-weekly exit site application of mupirocin (mupirocin group) vs no ointment (control group) on infection rates and catheter survival in patients receiving haemodialysis via a newly inserted, tunnelled, cuffed central venous catheter. Fifty patients were enrolled in the study. Both the mupirocin (n=27) and control (n=23) groups were similar at baseline with respect to demographic characteristics, comorbid illnesses and causes of renal failure. Compared with controls, mupirocin-treated patients experienced significantly fewer catheter-related bacteraemias (7 vs 35%, P<0.01) and a longer time to first bacteraemia (log rank score 8.68, P<0.01). The beneficial effect of mupirocin was entirely attributable to a reduction in staphylococcal infection (log rank 10.69, P=0.001) and was still observed when only patients without prior nasal Staphylococcus aureus carriage were included in the analysis (log rank score 6.33, P=0.01). Median catheter survival was also significantly longer in the mupirocin group (108 vs 31 days, log rank score 5.9, P<0.05). Mupirocin use was not associated with any adverse patient effects or the induction of antimicrobial resistance. 1

Experimental-Tx 148 catheters To evaluate the impact of  topical povidone-iodine ointment on the incidence of SCC related infections in hemodialysis patients. Catheter duration ranged from 2 to 210 days in both groups, with a mean of 38.6 days in T and 36.2 days in C (NS). Exit site (ES) infections were significantly less in T (5%) versus C (18%) (P less than 0.02); tip colonization (TC) was 17% in T versus 36% in C (P less than 0.01), while the incidence of septicemia (S) was also significantly less in T (2%) versus C (17%; P less than 0.01). S. aureus nasal carriers were at a threefold higher risk of SCC related septicemia (0.009/day) than noncarriers (0.003/day; P less than 0.05). The beneficial effect of PI ointment was most evident in this high risk group of S. aureus carriers: ES = 0% T versus 24% C, TC = 12% T versus 42% C, S = 0% T versus 29% C, P less than 0.05. There were no adverse effects of the treatment. 1

PLoS One. 2012;7(3):e32687. Observational-Tx 53 patients To compare the in-hospital mortality when the catheter is removed or not removed in patients with CR-BSI. 53 CR-BSI (37 diagnosed by the standard method and 16 by the conservative method) were diagnosed during the study period. There was a no statistically significant difference in the in-hospital mortality for the standard versus the conservative method (57% vs. 75%, p = 0.208) in ICU patients. 2

Observational-Dx 38 bloodstream infections To assess the validity of a test based on the earlier positivity of central venous blood cultures in comparison with peripheral blood cultures for predicting catheter-related bacteremia. A total of 22 patients had catheter-related bacteremias and 16 had noncatheter-related bacteremias, using the catheter-tip culture/clinical criteria as the criterion standard to define catheter-related bacteremia. Differential time to positivity of 120 min or more was associated with 86% sensitivity and 87% specificity. 2

Observational-Tx 404 cases of candidemia To review 404 episodes of candidemia that occurred in patients with cancer who have indwelling CVCs and determine by univariate and multivariate analyses the impact of CVC removal at various time points on the outcome of the bloodstream infection. Of the total 404 cases of candidemia, 241 (60%) were due to a primary source, 111 (27%) were catheter related, and 52 (13%) were secondary cases of candidemia caused by a source other than the catheter. Multivariate analysis showed that catheter removal < or =72 h after onset improved response to antifungal therapy exclusively in patients with catheter-related candidemia (P=.04). Clinical characteristics that suggested a noncatheter source for the candidemia were disseminated infection (P<.01), previous chemotherapy (P<.01), previous corticosteroid therapy (P=.02), and poor response to antifungal therapy (P<.03). 2

Ann Hematol. 2008;87(11):863-876. Review/Other-Tx N/A To present guidelines on central venous catheter-related infections in hematology and oncology. Positive blood cultures are the cornerstone in the diagnosis of CRIs, while local signs of infection are not necessarily present. Blood cultures should be taken from peripheral blood and from the venous catheter. A shorter time to positivity of catheter blood cultures as compared with peripheral blood cultures supports the diagnosis of a CRI. In many cases, a definite diagnosis requires catheter removal and microbiological analysis. The role plate method with semiquantitative cultures has been established as standard in most laboratories. Antimicrobial treatment of CRI should be directed by the in vitro susceptibility of the isolated pathogen. Primary removal of the catheter is mandatory in S. aureus and Candida infections, as well as in case of tunnel or pocket infections. Future studies will elucidate whether the rate of CRI in neutropenic patients may be reduced by catheters impregnated with antimicrobial agents. 4

J Vasc Interv Radiol. 1998;9(2):321-327. Observational-Tx 119 catheters in 68 patients To evaluate over-the-wire exchange of catheters through pre-existing subcutaneous tunnels as an alternative to catheter removal and de novo catheter replacement. Technical success for catheter exchange was 93%. Infection rates were comparable to those of de novo catheter placement: 0.15 and 0.11 infections per 100 catheter days for de novo and exchanged catheters, respectively. Catheter duration of function was not significantly different for de novo versus exchanged catheters: 63% and 51% at 3 months, 51% and 37% at 6 months, and 35% and 30% at 12 months, respectively. 2

Observational-Tx 48 episodes To evaluate the efficacy of ALT. A total of 801 long-term intravascular devices were placed in 105 patients during this period. There were 127 episodes of bacteraemia documented in these patients, with 92 being CRB. Of these, 48 episodes fulfilled inclusion criteria for the analysis. Nineteen episodes were treated with ALT plus systemic antibiotics, and 29 episodes were treated only with systemic antibiotics. Isolated microorganisms were similar in the two groups. The catheter had to be removed during therapy in one episode in the antibiotic-lock group and in seven episodes in the control group. Relapse of the bacteraemia with the same microorganism after stopping therapy was observed in two and three patients in the study group and the control group, respectively. Overall, successful treatment was achieved in 84% and 65% of the episodes in the antibiotic-lock group and the control group, respectively (P = 0.27). 2

Infect Control Hosp Epidemiol. 2004;25(8):646-649. Observational-Tx 72 cases of catheter-related GNB To study the characteristics of catheter-related, gram-negative bacteremia (GNB) and the role of central venous catheter (CVC) removal. Between January 1990 and December 1996, 72 cases of catheter-related GNB were available for review. Most of the patients (67; 93%) had their CVCs removed in response to the bacteremia. Few patients (5; 7%) retained their CVCs and were treated with appropriate antibiotics. When CVCs were removed, only 1 patient (1%) relapsed with the same organism, whereas all 5 patients with retained CVCs relapsed after having responded (P < .001). The most commonly isolated organisms were Enterobacter, Klebsiella, Stenotrophomonas, Pseudomonas, and Acinetobacter species. Catheter removal within 72 hours of the onset of the catheter-related GNB was the only independent protective factor against relapse of the infection (odds ratio, 0.13; 95% confidence interval, 0.02-0.75; P = .02). 2
